SPECIFICATION forming part of Letters Patent No. 313,356, dated March 3,1885.

7 Application filed May 21, 1884. (No model.)

To all whom it 11mg concern: v

Be it known that l, VVILLIAM MoOoNNELL MATHES, of Gatesville, Coryellcounty. in the State of Texas, have invented a certain new and usefulImprovement in Meat-Choppers, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming part of this specification.

This invention relates to a machine for either tendering or mincingmeat. It is for hand use, and automatically changes the position of themeat beneath the vertically-reciprocating knife or tendering-blade.

Figure 1 is a side View. Fig. 2 is an end view. Fig. 3 is a top view.Fig. 4 is a vertical section at 4 4:, Fig. 3. Fig. 5 is a detailtransverse section showing a tendering blade or device secured to thesash in place of the knife.

a is the frame of the machine. I) is the movable carriage or meat-boardcarried between supporting-rollers c and steadying-rollers d. Beneaththe meat-board are two racks, 6, whose teeth engage pinions f upon ashaft, g, that carries at its end aspur-wheel, h. iis abandcrank, whoseshaft 1" carries a spur-wheel, j, that engages with the wheel h, and aspurwheel, j, that engages with a pinion, is, upon a crank-shaft, Z, bywhich the sash is actuated. The crank m of the shaftl is connected by apitman or rod, n, with the sash o The sash works vertically in guides 19of theframeo.

The sash is formed for the attachment of the knife or tenderer r.

I propose to secure the blade to the sash in the following manner: sis ahorizontal tongue ofthe sash, that fits in a groove, t, of the blade, soas to prevent all vertical movement of the blade upon the sash. Theblade r is held firmly upon the tongue by clips u, held by screws o.

w are wires or rods extending across the machine parallel to the knifeor tendering-blade r. These wires or rods are movable. so that they maybe arranged in close proximity to the sides of either theknife ortenderingblade. As the former is thinner than the latter, it is obviousthat the rods or wires would require to be movable for the purposestated. The office of these wires is to prevent the blade r fromcarrying the meat upward with it as The wires or rods w have heads boardto pass beneath the blade, and at the same time causes the verticalreciprocation of the sash and knife or blade r. The knife may havesufficient depth to cutdown to the board, and thus mince the meat. Onthe other hand, aknife of less depth will not cut the meat quitethrough. so as to merely score the meat. Thedepth of cut would thusdepend on the depth of the knife.

WVhen it is preferred to bruise the meat, instead of scoring or cuttingit, a plain or serrated blade or bar, r, is used in place of the knife9", (see Fig. 5,) the wires or rods to being set a sufficient distanceasunder to admit the passage of the tenderingblade between.

It will be seen that by the oscillation or rotation of the haudcrank anypartof the meat may be brought beneath the sash and operated upon asmuch as may be desired.

The relative speed of movement of the sash 0 and meat table or board maybe regulated by changing the spur-wheels for others of different size.Thus the spur-wheel may be "changed for one larger and wheel j for onesmallerin diameter than shown to decrease speed of thesash.

I claim as my.i nvention 1. The combination of the frame havinghorizontal slots :0, a sash-having interchangeable cutting andtenderingblades, devices for operating the sash, and wiresor rods 10,adjustable in said slots to accommodate either blade. as set forth.

2. The combination of shaft 11 with spurwheelsjj, pinion 7c. crank-shaftZ, pitman n, sash 0, removable blade 1". shaft 9, carrying spur-wheel hand pinions f, and meat board or table I), with racks e, substantiallyas and for the purpose set forth.
